Informe actividad solar
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 345 Publicado el 2200Z a las 11 Dec 2007IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z Solar activity was very low. Today's activity consisted
of a few, low level B-class flares. Region 978 (S07E01) is the only
sunspot region on the disk and is a 240 millionths Eai beta-gamma
group. The group has been relatively stable during the past 24
hours. There appears to be a new region rotating around east limb
near N28.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low. There is a fair chance for an isolated C-class event
sometime during the next three days (12-14 December).
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
The geomagnetic field was mostly unsettled although there was an
active period from 10/2100Z-11/0000Z. Solar wind observations from
ACE show the onset of a co-rotating interaction region late
yesterday, followed by the onset of a high speed stream around
11/0000Z. Peak solar wind speeds were around 650 km/s. Nonetheless
the solar wind magnetic field has been relatively weak since
11/0130Z. The solar wind speed is currently declining slowly with
values around 550 km/s at forecast issue time.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominantly unsettled with a chance for an isolated
active period for 12 December. Conditions should be predominantly
quiet for 13-14 December.
